When Meyrick designated as type-species Phalaena aruncella Scopoli, 1763, Ent. Carniolica: 254, a nominal species not originally included in Micropterix he also, on page 7, placed podevinella, a nominal species originally included in Micropterix, as a junior subjective synonym of aruncella. Under the Code (Edn 3), Article 69(a)(v), this designation constitutes the fixation of the originally included nominal species as the type-species.

Unavailable designation of type-species: Phalaena aureatella Scopoli, 1763, a nominal species not originally included in Micropterix, and not linked in synonymy with one of the originally included nominal species when cited as type-species by Kirby, 1897, Handbk Order Lepid. 5: 315.

MICROPTERIX was included within the family MICROPTERIGIDAE by Kristensen (1999).
